We've got a new version of the RSS plugin that does a much better job of updating your RSS feed indexes.

1. Download the update here: http://www.x1.com/cs/X1WebServicesPlugin_chg17279.zip2. Extract the .X1i file to your hard drive
3. Open X1 and click on Tools > Options > Plugin Manager4. Click on Install New Plugin5. Navigate to the .X1i file that you saved in step 2 and click Open6. When asked if you want to replace the existing X1WebServicesPlugin, reply Yes6. If you already have a source (i.e. RSS feed) configured, you can simply choose No when asked to configure a source

Note: This will cause a reindex of your feed, but should be able to perform updates much better than previous versions.
